63512211 ÷ 7 
We want to divide 63512211 by 7.

Going ahead to step 1:
The number 7 fits into 6 0 times, leaving a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Include the next digit (3) from the dividend after 6, then repeat: 63 / 7

Moving on to step 2:
The number 7 fits into 63 9 times, leaving a remainder of 0.
Put 9 as the next digit of the answer. 
Result so far: 9.0
The remainder is 0 after subtracting 63 from 63.
Grab the next digit (5) from the dividend, add it to 0, then carry on: 5 / 7

On to step 3:
7 can be fit into 5 0 times, resulting in a remainder of 5.
The next digit of our result is 0. 
Result so far: 90.0
Subtracting 0 from 5 leaves us with 5.
Fetch the next digit (1) from the dividend, attach it to 5 and continue: 51 / 7

Going ahead to step 4:
51 divided by 7 is 7 with a remainder of 2.
Use 7 as the next digit of our solution. 
Result so far: 907.0
Subtracting 49 from 51 leaves us with 2.
Bring next digit (2) of the dividend behind the 2 and repeat the process: 22 / 7

Advancing to step 5:
If we divide 22 by 7, we get 3 and a remainder of 1.
Record the quotient 3 as the next digit in the result. 
Result so far: 9073.0
Deduct 21 from 22 and we're left with 1.
Bring next digit (2) of the dividend behind the 1 and repeat the process: 12 / 7

On to step 6:
12 divided by 7 is 1 with a remainder of 5.
Put 1 as the next digit of the answer. 
Result so far: 90731.0
Deduct 7 from 12 and we're left with 5.
Take the next digit (1) from the dividend and append it to 5, then repeat: 51 / 7

Advancing to step 7:
When dividing 51 by 7, we get 7 with a remainder of 2.
Write down 7 as next digit of the result. 
Result so far: 907317.0
Subtract 49 from 51 to get 2.
Take the next digit (1) from the dividend and append it to 2, then repeat: 21 / 7

Going ahead to step 8:
21 divided by 7 is 3 with a remainder of 0.
The number 3 becomes the next digit in our result. 
Result so far: 9073173.0
Deduct 21 from 21 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 9:
0 divided by 7 is 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 9073173.0
Deduct 0 from 0 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 10:
7 can be fit into 0 0 times, resulting in a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 9073173.0
Deduct 0 from 0 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final outcome is 9073173.0, with a leftover of 0.0.
